Trier will wait for Knicks spot

David Fizdale said undrafted rookie guard Allonzo Trier’s two-way contract will not be ripped up until, at the earliest, after his 45 days of service is completed on the Knicks roster. Trier still can play, but technically will not be on the 15-man roster when it is set Monday.

Trier had a scintillating training camp, posting a 25-point night and an 18-point evening. But he came back to earth Friday in the Knicks’ 113-107 loss to the Nets in their final preseason game. After averaging 15.8 points in 22.6 minutes and boasting the team’s secondhighest preseason scoring average, Trier scored just eight points and shot 2-for-9 against the Nets.

“We have 45 days of him working with us to figure out what’s the next move,’’ Fizdale said before the game. “We are in the process of working with that and finding the best way to stretch that out. Obviously the kid has shown he’s an NBA basketball player. It’s a matter of us doing it in a way that’s best for the team. He’s showing he just has a knack for putting the ball in the hole and showed he’s a competitor defensively.”

Delaying the decision will enable the Knicks to wait before cutting any of the guaranteed contracts until sometime in mid-December. That is, other than the stretch provision waiver of Joakim Noah by Monday’s roster cut-down day — a forgone conclusion for several weeks.

It’s obvious Trier, unless he gets hurt, is deserving of a 15man spot, but the Arizona product’s two-way contract calls for him be on the Knicks roster just for 45 days. The clock doesn’t start ticking, however, until G-League training camp commences Oct. 27.

“It doesn’t really matter to me,’’ Trier told The Post. “I trust they’ll do what’s best for the situation. Whatever timetable, they’ll do it when they feel it’s the right time.:

➤ Regarding the new 14-second shot-clock rule after an offensive rebound, Fizdale said: “I like it. We all like it. It speeds the game up. You can’t just set up and drain the clock another 24 seconds.’’
